That’s a bit complicated. Account handling is by nature of federation, linked to your source instance. There is discussion on GitHub about moving account export up the chain just to help people move from lemmy.ml to other instances.
Keep that discussion pinned and if you want you can see if you can help with a PR if you’re able.
Even then this would just let you download your data, not necessarily migrate it to another instance because each instance runs with it’s own Postres database and the user comments and such on that instance are linked to that database. So if that database goes, that data goes.
Equally? Exponentially.
Anyone who’s worked private sector, especially as a subcontractor, knows that private industry is entirely bloat. For every one productive hour of labor, there’s 10 hours of bullshit middle management and admin work.
